Net Run Rate (NRR) Calculator for Cricket

A team that scores 172 in 19.3 overs, after conceding 170 in 20 overs, has a net run rate of +0.321. Enter the runs and overs for both sides to see the run rate for, the run rate against and the NRR.

Understanding the Concept

Net run rate (NRR) is the tie-breaker used in most cricket league tables, including ICC tournaments and the IPL. When teams finish on the same points, the one with the higher NRR ranks higher. NRR is the team's scoring rate minus its opponents' scoring rate: runs scored per over faced, minus runs conceded per over bowled. A positive NRR means the team scored faster than its opponents on average. Overs are written in cricket notation, where the digit after the point is balls, not tenths. 19.3 overs means 19 overs and 3 balls, which is 19.5 overs as a decimal. The calculator converts this for you; the ball count must be 0 to 5. Under ICC playing conditions, if a team is bowled out before its quota, the full quota of overs (for example 20 in a T20) is used for its overs faced, not the overs actually played. So enter 20, not the overs at which the last wicket fell.

How to Use the Net Run Rate Calculator

  • 1
    Enter runs scored and overs facedFor your team. Use cricket notation, such as 19.3. If your team was bowled out, enter the full quota.
  • 2
    Enter runs conceded and overs bowledFor your opponents. If you bowled them out, enter the full quota of overs.
  • 3
    Read the NRRSee the run rate for, the run rate against and the net run rate to 3 decimal places.
  • 4
    For a tournament, use totalsAdd up runs and overs from all matches first, then enter the totals.

Calculation Formula & Mathematical Definition

NRR = (Runs scored ÷ Overs faced) − (Runs conceded ÷ Overs bowled)

Overs are converted to decimals first: overs + balls ÷ 6, so 19.3 becomes 19.5. For a tournament, sum all runs and all overs across matches before dividing; do not average the NRRs of individual matches.

Variable Definitions

  • Runs scored=Runs for: Total runs your team scored
  • Overs faced=Overs batted: Overs your team batted (full quota if bowled out)
  • Runs conceded=Runs against: Total runs your opponents scored
  • Overs bowled=Overs bowled: Overs your team bowled (full quota if opponents were bowled out)

Step-by-Step Worked Example

Chase won in 19.3 overs

Input Parameters:
Runs scored: 172Overs faced: 19.3Runs conceded: 170Overs bowled: 20
Calculation Steps:
  1. 19.3 overs = 19 + 3/6 = 19.5 overs.
  2. Run rate for = 172 ÷ 19.5 = 8.821.
  3. Run rate against = 170 ÷ 20 = 8.500.
  4. NRR = 8.821 − 8.500 = +0.321.
Final Result:NRR +0.321.

Two matches combined

Input Parameters:
Match 1: Scored 180/20 ov, conceded 165/20 ovMatch 2: Bowled out for 150 in 18.2 ov; opponents chased 151 in 17.4 ov
Calculation Steps:
  1. Bowled out, so overs faced in match 2 count as 20.
  2. Totals: scored 330 in 40 overs; conceded 316 in 37.667 overs (17.4 = 17.667).
  3. Run rate for = 330 ÷ 40 = 8.250; against = 316 ÷ 37.667 = 8.389.
  4. NRR = 8.250 − 8.389 = −0.139.
Final Result:Tournament NRR −0.139.

Practical Scenarios & Nuances

League tables: work out where your team stands when points are level.

Qualification scenarios: test how big a win you need, such as chasing a target within a set number of overs.

Local and school tournaments: calculate NRR for your own league without a scorer's app.

Common Mistakes to Avoid

Treating 19.3 overs as 19.3 decimal overs instead of 19.5.

Entering the overs at which a team was bowled out instead of the full quota.

Averaging match NRRs instead of using total runs and total overs.

Frequently Asked Questions

How is net run rate calculated in cricket?

Divide the runs your team scored by the overs it faced, then subtract the runs it conceded divided by the overs it bowled. 172 in 19.3 overs against 170 in 20 overs gives +0.321.

What does 19.3 overs mean in NRR?

19 overs and 3 balls, which is 19.5 overs as a decimal because an over has 6 balls.

What happens to NRR if a team is all out?

Under ICC rules the team is charged its full quota of overs, such as 20 in a T20, even if it was bowled out earlier.

How is NRR calculated over a tournament?

Add up all runs scored and overs faced across matches, and all runs conceded and overs bowled, then apply the formula to the totals.

Is a negative NRR bad?

It means opponents scored faster than your team on average. It only matters when teams are level on points.
